Crowcon FGard H2 Multi-Spectrum IR Hydrogen Flame Detector

The Crowcon FGard H2 flame detector is an explosion-proof, multi-spectrum IR hydrogen flame detector. The FGard H2 delivers superior performance, responding to hydrogen fires at long distances.

Crowcon FGard H2 Key Features:

Multi-Spectrum IR design delivers long detection distances and enhanced false alarm immunity
Continuous optical test, without a reflector - Verifies operation and improves device up-time
Microprocessor-controlled heated optics - Maintains operation in harsh weather conditions (snow, ice, condensation)
International hazardous area approvals - FM / ATEX / IEC Ex / INMETRO* / PESO*
Certified performance testing to multiple fuels - FM 3260, EN 54-10
Adjustable sensitivity levels - For application flexibility, Ensure detectors do not cross-vote
External testing with a long-range flame simulator - Minimises the need for scaffolding
Easy integration using industry-standard outputs: Alarm and Fault Relays, • 0-20mA, • HART® 7, as standard
Certified SIL 2 capable
5-year warranty

The FGard H2 has been independently tested to demonstrate it can detect a hydrogen plume fire at 40m (131ft) in less 5 seconds. The FGard H2 delivers superior detection performance of hydrogen fires, utilising the latest hydrogen flame detection algorithms to ensure maximum false alarm immunity.
